Annona emarginata (Annonaceae) has two morphological variations (A. emarginata ‘mirim’ and A. emarginata ‘terra-fria’). The species has agricultural value and produces specialized metabolites of pharmacological interest. The objective of this work was to analyze whether chemical and morphological differences contribute to differentiate A. emarginata ‘terra-fria’ from A. emarginata ‘mirim’, as chemophenetic variations of A. emarginata. The analysis of chemical compounds was based on the quantification, profile of root alkaloids and on the leaves volatile profile, together with morphometric analyses of the leaf blade. The samples were collected in three phenological stages (flowering, fruiting, and vegetative) at two places in São Paulo, Brazil. Differences in the composition of the alkaloid profile and leaf volatiles (in both places and in the three phenological stages) allowed us to separate the two morphotypes by multivariate statistical analysis. These differences agreed with the leaf blade morphology and flower color. This first chemophenetic report of A. emarginata demonstrates that, in addition to morphological variations, the specialized metabolism of roots and leaves can be phytochemical characters, which suggest the existence of at least morphochemotypes of A. emarginata.

化学表型作为区分 Annona emarginata (Schltdl.) H. Rainer 形态型的工具

Annona emarginata（番荔枝科）有两种形态变异（A. emarginata 'mirim' 和A. emarginata 'terra-fria'）。该物种具有农业价值并产生具有药理意义的特殊代谢物。这项工作的目的是分析化学和形态差异是否有助于区分A. emarginata 'terra-fria' 和A. emarginata 'mirim'，作为A. emarginata 的化学表型变异. 化合物的分析基于根生物碱的定量、分布和叶片挥发性分布，以及叶片的形态测定分析。在巴西圣保罗的两个地方，在三个物候阶段（开花、结果和营养）收集样品。生物碱谱和叶挥发物（在两个地方和三个物候阶段）组成的差异使我们能够通过多变量统计分析将两种形态类型分开。这些差异与叶片形态和花色一致。A. emarginata 的第一份化学表型报告表明，除了形态变异外，根和叶的专门代谢可以是植物化学特征，这表明至少存在A. emarginata 的形态化学型。
